This report presents a comprehensive analysis of TCP/IP networking, focusing on a network design for an M2M solution with 1200 nodes. It details the use of a private IP address scheme (10.1.1.1), subnetting with VLSM, and the implementation of a central router and switches. The report addresses network security concerns such as cabling plans, disabling unused ports, and the use of firewalls and access control lists. It also covers the reconfiguration of subnets to accommodate an increased number of hosts. Furthermore, the report explores network protocols like HTTP, FTP, and SMTP and the role of a network analyzer tool, specifically Wireshark, including its benefits, associated costs, and usability. The report recommends the use of Wireshark for analyzing data packets and monitoring network traffic, providing a valuable resource for understanding and optimizing network performance. The report concludes with a discussion on network configurations, addressing the significance of understanding data flow and configurations for efficient network management.
